Gemstone Cat’s Eye associated to planet Dragon’s Tail; it is the planet of ultimate spiritual awakening. Planet Ketu indicates the false arguments, bonding, restlessness, wondering speech, conspiracy, black magic, tantra, smoking habits, dreams, wicked thoughts, swelling in the body, empires, states, and philosophy. When weak, it causes doubt, uncertainty, poor discrimination, poor concentration or lack of insight. It is the planet of ultimate spiritual awakening. It causes tendencies that appear to be like a weak Ascendant. But as a weak Rahu brings lack of clarity and a clouding of perception, a weak Ketu brings doubt and questioning. The gem should be used with caution if the person is high in Pitta, as under the description for Mars, or if Ketu is in a sign of a planet that is weak or afflicted.
